(54) SLANTED LOADING FOR LINE REPLACEABLE MULTIPOINT FUEL INJECTOR ARRAYS


(57) A system includes an engine case (102) for a gas turbine engine defined around a longitudinal axis. A plurality of access openings are defined through the engine case (102). A combustor (108) is housed in the space inside the engine case (102). The inner annular wall (110) of the combustor (108) includes a first rail on an upstream end thereof with a radially outward opening slot. The outer annular wall (112) of the combustor (108) includes a second rail on an upstream end thereof. A plurality of circumferentially spaced apart dome liners extending from the first rail to the second rail. Each dome liner extends tangentially in a direction oblique relative to a radius extending from the longitudinal axis. A plurality of multipoint fuel injector components are assembled across the first and second rails to from a combustor dome together with the dome liners.
